Sales are up a staggering 6329% on the Xbox 360 version as of writing and it's now 17 on Amazon's sales rank. It was previously 1,093. The number two game, up 1877% is the game of the year edition that includes the Undead Nightmare DLC.

Update: Amazon's percent change listings don't appear to refer to sales specifically, but instead to the sales rank of the item (via Twitter user ZhugeEX) . So Red Dead Redemption isn't selling 6,329% more copies, its rank in Amazon's PC and video game sales category just went up by that much. Still notable, but not quite the same thing.

It's now available for £10.49 on Amazon but if you don't care for the physical edition, it's currently on sale on the Xbox Store for the incredibly reasonable price of £8.74. Regardless of the way you want to get your sharp shooting hands on it, it'll be available to play on Xbox One this Friday.
